Underground Genesis

In a world ravaged by World War III, an atomic bomb veers off course, detonating over an island teeming with discarded waste. The explosion triggers an unprecedented chemical reaction, releasing a mutagenic steam that blankets nearby islands. This steam radically alters the DNA of the local fauna, transforming ordinary animals into colossal, aggressive beasts.

With these new predators roaming the surface, 80% of humanity is decimated, forcing the survivors to seek refuge underground. In this subterranean world, they adapt, learning to live without the advanced weaponry of the past. As time passes, the remnants of humanity devise ways to fight back against the monstrous creatures that have claimed the land above. "Steam of the Beast" is a tale of survival, adaptation, and the enduring human spirit's fight against the odds in a world where nature has turned against them.
